SYNCHRONIZING MEANS FOR MOVING PICTURE AND TALKING MACHINES Filed Marchl0, 1927 Patented Sept. 24, 1929 LOUIS KOVAES, OF THROOP, PENNSYLVANIASYNCHRONIZING MEANS FOR MOVING PICTURE AND TALKING MACHINES Applicationfiled March 10, 1927.

This invention relates to a new and useful device in the nature of acombined moving picture and talking machine, adapted particularly foruse-in theatres, public halls, lecture rooms, and the like, as a meansof projecting moving pictures on a screen and reproducing any desiredaccompanying dialect, lecture, or descriptive talking, as may berequired to more fully convey the meaning or theme of the. movingpicture.

The object of the invention is to provide a combined moving picture andtalking machine of novel construction and arrangement of parts,hereinafter more fully described,

' claimed and illustrated in the accompanying drawing.

Fig. 1 illustrates my improved combined moving picture and talkingmachine, as same would appear when installed in a theatre ready for use.

Fig. 2 is a side elevational detail view of the adjustable magazinestand adapted to hold the records.

Fig. 3 is a transverse vertical sectional view taken on the line 33 ofFig. 2.

Fig. 4 is a detail central sectional view of the clutch mechanism forsynchronizing the moving picture and talking machine reproduction.

As here embodied my improved device comprises a moving picture machine10, of ordinary construction such as generally used, having a projector11, by which any desired moving picture may be projected upon a screen12. The moving picture machine 10, is mounted on a base 12, providedwith lower extended elements 13, or legs, adapted to support the saidmoving picture machine. The talking machine 14, or phonograph, is housedin a suitable case, and is provided with a cover 15, preferably ofglass, celluloid, or the like, so as to provide a dust proof removablecover member.

In Fig. 1 of the accompanying drawing, 1 have shown my improved devicein place, on an elevated platform 16, and I have provided a stairway 17,as a means of egress thereto. The latter described elements, beingcommon to a public hall, theatre or the like, which is provided with theusual. seats 18, and

Serial No. 174.187.

the boxes 19 for reserved seating arrangement.

The talking machine 14, is providedwith the loud speaker 20, operativelyconnected thereto, and provided with the usual magnifying means, so asto produce the required volume. The ear phones 21. are operativelvconnected to the talking machine 14 and are conveniently located in theabove mentioned boxes 19, adjacent to the seats so as to permit theoccupants of the seats 22, in the boxes l9, to easily hear the talkingmachine 14.

In Figs. 2 and 3 of the accon'ipanying drawing, I have shown the talkingmachine 14, provided with the usual reproducer 23, and needle 24,removably attached thereto, in the ordinary well-known manner. Thereproducer 23, is mounted on the free extremity of the reproducer arm25, pivotally attached as at 26, to the case 27.

The. records 27, such as ordinarily used in talking machines, are ofhollow cylindrical construction, and are adapted to remo'vably engagethe extended elements 28, or arms rotatively attached to and eXtendedhorizontally from the spider member 29. The pinions 30, are attached tothe arms 28, and mesh with the gear 31 attached to the arms 28, and meshwith the gear 31, attached to the shaft 32. The shaft 32, rotativelysupports the spider member 29. The shaft 32, is rotatively mounted inthe bracket 33, at-' tached to the case 27'. The sprocket wheel 34, isattached to the shaft The above described construction being such. aswill permit the records 27, to be rotated when the sprocket wheel 34 isrotated.

The lever 35, is pivotally attached, at one extremity, as at 36, by apin, or the like, carried in the bracket 37, attached to the case 27.The lever 35, is provided with a handle element 38, at its freeextremity, and is provided with a raised intermediate portion 39,adapted to engage any desired one of the notches 40, formed in thespider member 29, adjacent to the arms 28. The lever 35, is normallyheld in the above mentioned engagement, by means of the expansion spring41, positioned under the lever 35. The latter described constructionbeing such as will per- -rnit any desired one of the records 27, to beheld in the required position, so as to permit the needle 2 1 of thereproducer 23, to make contact therewith, as clearly shown in Fig. 3, asis required to play the record.

In Fig. 5 of the accompanying drawing, I have shown the operating handle50, of the moving picture machine 10, attached to the crank 51, which ispivotally attached, as at 52, by a pin or the like to the shaft 53. Thereel 54: such as commonly used to carry the film 55, such asordinarily'used in moving picture machines, and which contains the viewsof the moving picture, is attached to the shaft 53. The aboveconstruction being such as will permit the handle 50, when turned orrotated, to move or travel the film 55, which in conjunction with theordinary commercial elements of the above mentioned moving picturemachine 10, projects the moving picture on the screen 12, visible to theaudience.

In Fig. 4. of the accompanying drawing, I have shown the disc member 56,rotatively mounted on the shaft 53. The ring shaped member 57, isattached to the disc member 56,

and has formed, or cut on its outer periphery sprocket teeth 58, overwhich the sprocket chain 59,-is extended. The sprocket chain 59, is alsoextended over theabove mentioned sprocket wheel 34. The ring shapedmember 57 is provided with a tapered, or frustum conical shaped portion60, adapted to be engaged by the cover member 61, which has attachedthereto a facing 62, preferably of leather, or the like. The cone member61, is slidably mounted on the shaft 53, and is attached thereto, bymeans of the keys 62, at-

tached to the shaft 53, and extended therefrom, engaging. in recessesformed in the hub 63, of the cone member 61. The expansion spring 64, iswound or positioned on the shaft 53, intermediate the collar 65,attached to the shaft 53 and the hub 63, of the cone member 61, so as tonormally hold the cone member 61,

in engagement with the ring shaped member 57. The above describedconstruction being such as will permit the handle 50 when rotated, torotate the above mentioned talking machine records 27, and to moveortravel the ,reel 55, as above set forth. The crank 51,. is

provided with an extended portion 66, adapted to engage or strike thecone member 61, so as to disengage the cone member 61,

' with the ring shaped member 57, when the handle 50, is pressed orforced inwardly. The

above described construction being such as ther inwardly than abovementioned, to engage the ring shaped member 57, so as to ing of the saidtalking machine and moving picture machine.

It being understood that the talking machine 14,-is provided with theusual speed regulator 14.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is as follows:

1. The combination with a driven member, of a shaft firmly connectedwith said driven member, a disc member rotatively mounted on the shaft,a ring member attached to the disc for driving a second member, andformed with sprocket teeth, said ring member being provided with afrustum conical portion, a cone member keyed to the shaft and slidablymounted and capable of frictionally engaging the frustum conicalportion, means for normally urging these parts into engagement, a crankconnected with the shaft, and an ex tended portion thereon abuttableagainst the cone member upon depression of the crank to disengage thecone member from the conical portion so as to permit the sprocket chainto stand still so as to synchronize the driven member therewith.

Q. The'combination with a driven member, of a shaft firmly connectedwith said driven member, a disc member rotatively mountedon the shaft, aring member attached to the disc for driving a second member, and formedwith sprocket teeth, said ring member being provided with a frustumconical portion, a

cone member keyed to the shaftand slidably mounted andcapableoffrictionally engaging the frustum conica'l portion, a sprincoaxially arranged on the shaft and acting be tween the cone member anda flange .on the shaft for normally urging the cone member intoengagement'with the said frustum conical portion; a crank connected withthe shaft,

and an extended port'ion thereon, abuttable against the cone member upondepression of the crankto disengage'the cone member from the conicalportion so as to permit the sprocket chain to stand still so as tosynchronize the driven member therewith.

In' testimony whereof I have afiixed my signature.
